What modifications were necessary to make it a 650B? Did you have to change the shock or add anything special? I'm considering buying one of those frames and doing the same thing. How do you like the ride of that bike?

Negative rep? What the heck is that? I thought these forums are for guys like us to speak freely sbout our personal opinions. If you disagree, then post a reply in the thread. guys who leave neg rep on here, are probably the same guys who leave negative feedback on ebay before even contacting the seller. Everything can be resolved with communication. Sorry for ranting..I deal with that kinda stuff everyday.. Doesn't seem fair.

Regardless, thumbs up on the new build. Most of us 29ers still enjoy the smaller wheels and/or plan on building a 650b. Its a good wheel size. I see it in my near future. Thanks for sharing it...Any idea of the total weight?

Although i do agree that this in the wrong forum giving you negative rep for posting here does not sound right to me.
Seems like you made the right call with the 27.5 for a long travel bike and your "style". Though i love my superlight29 if i build a 130mm+ bike 650b is where i will most likely end up also.
Have fun on the trails!
